Online Metal Trace Analysis System




The OVA 7000, OVA7000 Dual Cell and OVA5000 utilize internationally recognized voltammetry (ASV and CSV) technology, which provides quick and accurate determination of metals at the micrograms per liter (ppb) level, directly comparable with laboratory analysis using AAS or ICP. They can provide real-time monitoring of several concurrent sample streams, configured to individual customer requirements. Sample pre-treatment may include digestion for elimination of potential interferences, although ASV is not affected by aluminum, sodium, calcium, magnesium, chlorine or other salts, often present in industrial samples which can cause problems with other analysis methods.

Key features :

  • 24 hour monitoring of up to 3 sample streams in effluent or (6 in drinking water)           
  • Pre-treatment options of acid/UVdigest to eliminate interferences and allow total and dissolved concentrations to be monitored.
  • Modular construction
  • Results stored on solid-state internal memory
  • Programmable alarm outputs for out-of-range samples or system faults
  • Solid electrodes – no hazardous elemental mercury
  • Multi-element analysis configurations available.
